The volatile Bitcoin has had its share of controversies and exchange shutdowns as the currency matures. Companies like Overstock.com, Newegg, Expedia and some Amazon storefronts accept Bitcoin as a form of payment. But major retailers like Walmart and eBay have not warmed up to the idea yet. The value of one bitcoin was around US$630 as of Friday, according to multiple cryptocurrency websites.

There are some advantages to paying via Bitcoin. The form of currency is accepted around the world, and for Dell, the payment-processing cost is less than with credit cards.

But the form of payment has its quirks.

“Due to the nature of the Bitcoin network, once you initiate a Bitcoin transaction you cannot change or cancel it,” Dell said on a terms and conditions page.

Customers could seek refunds in the case of canceled transactions or product returns.

“For a qualifying return of product paid for in Bitcoin, any refund due will be remitted to the purchaser via check in U.S. Dollars for the full amount of the purchase price paid at the time of the original transaction, less any applicable restocking fees,” Dell said.
